It should be noted that the preset voltage threshold, the preset frequency threshold and the preset time threshold in the control module 30 may be set arbitrarily, and are not limited herein. In addition, the preset voltage threshold, the preset frequency threshold and the preset time threshold in the control module 30 may be not only point values but also ranges, and are not limited herein. If the range is reached, it is determined whether the magnitude of the electrical pressure signal output from the at least one pressure monitoring membrane 10 and the frequency of the electrical pressure signal output from the at least one pressure monitoring membrane 10 are within the corresponding ranges, so as to determine whether to output the alarm control signal to the wireless transceiver module 50.

It should be understood that the number of signal preprocessing modules 31 should be the same as the number of outputs to which the at least one pressure monitoring membrane 10 is connected. For example: if the number of the at least one pressure monitoring membrane 10 is one, i.e. there is one set of output terminals, the number of the signal preprocessing modules 31 is one; if the number of the at least one pressure monitoring film 10 is three, and the three pressure monitoring films are independently connected, and each pressure monitoring film has one group of output ends, that is, three groups of output ends, the number of the signal preprocessing modules 31 is three; if the number of the at least one pressure monitoring film 10 is three and the at least one pressure monitoring film has two groups of output ends after being connected in series and/or in parallel, the number of the signal preprocessing modules 31 is two; by analogy, the description is omitted here.

It should be understood that the alarm device based on the pressure monitoring membrane of the first embodiment uses the self-contained power supply in the control module 30 to supply power to each module, which is not shown in the figure, and of course, a person skilled in the art may also separately provide a power supply module to supply power to each module externally, which is not limited herein.

Specifically, when the power module is separately provided to supply power to each module, the power module is connected to the control module 30 through the switch module 20, and when the power module supplies power to the control module 30 is controlled through the switch module 20. More specifically, when the power module is separately provided to supply power to each module, the power module is connected to the central control module 32 through the switch module 20, and when the power module supplies power to the central control module 32 is controlled through the switch module 20.

When the user uses the alarm device based on the pressure monitoring membrane of the first embodiment, the user first needs to turn on the switch module 20 to start the operation of the control module 30 (i.e. the signal preprocessing module 31 and the central control module 32).

When pressure acts on at least one pressure monitoring film 10, at least one pressure monitoring film 10 converts the pressure into a pressure electric signal and outputs the pressure electric signal to the signal preprocessing module 31; the signal preprocessing module 31 is configured to receive the electrical pressure signal output by at least one pressure monitoring membrane 10, preprocess the electrical pressure signal, and output the preprocessed electrical pressure signal to the central control module 32.

If the preset voltage threshold value in the central control module 32 is 50V, the preset frequency threshold value is 2Hz, and the preset time threshold value is 1s, when the central control module 32 monitors that the magnitude of the pressure electric signal output by the signal preprocessing module 31 is greater than or equal to 50V in 1s and the frequency of the pressure electric signal output by the signal preprocessing module 31 is greater than or equal to 2Hz in 1s, it is determined that the user is fighting, an alarm control signal and a positioning start instruction are generated, and the alarm control signal and the positioning start instruction are correspondingly output to the wireless transceiving module 50 and the positioning module 40 respectively; when the central control module 32 monitors that at least one of the pressure electric signals output by the signal preprocessing module 31 in 1s is smaller than 50V and the frequency of the pressure electric signal output by the signal preprocessing module 31 in 1s is smaller than 2Hz, judging that the user does not fight, generating no alarm control signal and positioning starting instruction, and continuing to monitor and judge for the next time; when the central control module 32 monitors that the magnitude of the pressure electric signal output by the signal preprocessing module 31 is greater than or equal to 50V in 1s and the frequency of the pressure electric signal output by the signal preprocessing module 31 in 1s is less than 2Hz, judging that the user does not fight, generating no alarm control signal and positioning starting instruction, and continuing to monitor and judge for the next time; when the central control module 32 monitors that at least one of the pressure electric signals output by the signal preprocessing module 31 in 1s is smaller than 50V and the frequency of the pressure electric signal output by the signal preprocessing module 31 in 1s is greater than or equal to 2Hz, it is determined that the user is not fighting, the alarm control signal and the positioning start instruction are not generated, and the next monitoring and determination is continued.

When the positioning module 40 receives the positioning start instruction output by the central control module 32, it generates positioning information according to the positioning start instruction and outputs the positioning information to the central control module 32.

After receiving the positioning information, the central control module 32 outputs the positioning information to the wireless transceiver module 50; after receiving the alarm control signal and the positioning information, the wireless transceiver module 50 sends the alarm control signal and the positioning information to the terminal device for alarming.

When the user turns off the switch module 20 and the control module 30 stops operating, the alarm device based on the pressure monitoring membrane will be in an inoperative state.
